Soil and/or slope instability; Terrain prone to erosion; Ecological impacts, habitat destruction, terrestrial and/or aquatic biological losses. [3] Drainage problems (surface and/or subsurface flow) for areas not considered in the regrading plan. [8] Loss of aesthetic natural landscape topography and/or historical cultural landscapes.
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
The Texas Land Survey System is often measured in Spanish Customary Units. The most important of these is the vara , which, while ambiguous in the past, was legally established to be exactly 33 + 1 ⁄ 3 inches (846.67 mm) long in June 1919.

Soil improvement (fertilization, establishment of a productive chemical balance). Road construction; Oil palm plantation and rainforest fragment on Borneo. Because the newly created farmland is more prone to erosion than soil stabilized by tree roots, such a conversion may mean irreversible crossing of an ecological threshold
[34] [35] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [36] [37] [38] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
Tillage erosion is the soil movement and erosion by tilling a given plot of land. [3] A similar practice is contour bunding where stones are placed around the contours of slopes. Contour plowing has been proven to reduce fertilizer loss, power, time consumption, and wear on machines, as well as to increase crop yields and reduce soil erosion.
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):
